JOHN BERRY, OF NOTTINGHAM, ENGLAND.

MACHINE FOR MAKING BRICKS, TILES, 80C.

SPECIFICATION forming part of Letters Patent No. 614,690, dated November 22, 1898.

Application filed July 31, 1397. Serial No. 646,696. (No model.)

To all whom it ntcty concern.-

Be it known that 1, JOHN BERRY, a subject of the Queen of Great Britain and Ireland, residing at Nottingham, England, have invented new and useful Improvements in Machines for Making Bricks,Tiles, and the Like, of which the following is a specification.

This invention relates to an improved brick or tile making machine in which the clay is automatically subjected to the various operations of mixing, filling into the molds, and cutting off, and finally delivering the same ready for compressing into a finished brick, said operations being performed by mechanism comprising a single organized and continuously-operating machine.

My invention will be readily understood on reference to the accompanying drawings, in which- Figure 1 is a plan and Fi 2 a side View of a brick or tile making machine constructed in accordance with my invention. Figs. 3 and 4 are aface view and end View, respectively, of the brick-mold or die-plate. Figs. 5 and 6 are respectively a front view and a vertical section of the box or frame in which the mold works. Fig. 7 is a plan View, and Fig. 8 a view in elevation, of the cam or wiper for actuating the mold or die-plate. Fig. 9 is a detail view of one of the adjustable pug-mill blades; and Fig. 10 is a detail sectional view of one of the plnngers or rams, showing the flannel cover.

ct is the pug-mill, driven from a shaft a, fitted with the usual fast and loose pulleys and with suitable gear-wheels for giving motion to the pug-mill shaft and to other parts of the machine. I

The adjustable pug-mill blades b are inserted by their stems Z) into holes in the pugmill shaft 11 and are capable of being set at any angle relatively to this shaft.

At the mouth of the pug-mill is the box or frame a, in which slides the die-plate or brickmold c. This mold is provided with two openings 0 c of the size of the brick or tile to be formed, it being further provided with a slot 0*, in which works a die cl for supporting the said mold in its box or frame 0. This sliding mold is kept in proper contact with the mouth 0 of the pug-mill by means of adjustable plates 6 6, so insuring the clay being out clean off on issuing from the mouth of the pug-mill.

In Fig. 1 the mold c is shown inside the box 0 and is supposed to be filled with clay, in a plastic condition, from the pug-mill through the action of the revolving blades 1), while the mold c is supposed to have delivered a molded brick by the action of a ram or plunger 9. The plungers g g for clearing the molds c and 0 respectively, are located on each side of the pug-mill month. These plungers, which are covered, preferably, with flannel and arranged to be automatically lubricated from an oil-reservoir g", are actuated by lever-arms on a rocking shaft 9 and are caused to advance and retire simultaneously; but only one at a time acts on a molded brick, while the other remains idle. They receive their forward movement through the medium of cams or inclines g on the spur- .wheel 9 which act against rollers g The backward movement of said plungers takes place immediately after the completion of the forward movement by means of a cam or incline 9 arranged at the opposite side of the spur-Wheel g and acting on a roller 9 The cams or inclines g situated diametrically opposite the cams g and g on the Wheel 9", allow of the plungers g g being operated twice during each revolution of said wheel.

The spur-wheel g is driven by a pinion h on the shaft h, which receives motion from the pulley-shaft a. A cam or wiper h fixed on the shaft h of the spur-wheel g acts on a pin 7' provided on the bar j attached to the brick-mold, and so causes the mold c in its turn to enter the box a and permit the brick .to be ejected from the mold c by the plunger g.

The molded bricks, which are alternately delivered at one or the other side of the pugmill, are removed by endless bands 70 k and delivered by the latter to the pressing mechanism, which it is unnecessary to describe, as the same will form the subject-matter of a separate application for patent.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. In a machine for making bricks, tiles and the like, the combination with a pugmill shaft square in cross-section, of adj ust IOU able blades having threaded shanks passing through holes in said shaft and provided with shoulders resting against the square sides of the shaft, and nuts screwed over the threaded ends of the shanks for securing the blades in their adjusted positions, substantially as described.

2. In a machine for making bricks, tiles and the like, the combination with the pugmill, its shaft, and adjustable blades, of a mold guide-box fixed to the mouth of the pugmill, a vertically-arranged sliding mold having openings adapted to receive and cut off a predetermined quantity of clay and having a longitudinal slot, and a die attached to the mold guide-box and passing through the said slot in the sliding mold, substantially as described.

3. 111 a machine for making bricks, tiles and the like, the combination with a guidebox at the mouth of the pug-mill, of the vertically-arranged mold sliding in said guidebox, and adjustable plates arranged inside said guide-box and bearing against the sliding mold, substantially as described.

4. In a machine for making bricks, tiles and the like, the combination with a sliding mold and its guide-box, of a reciprocating plunger for expelling the clay from said mold, two laterally-projecting autil'riction-rollers arranged on a movable part of the plunger, a wheel arranged to rotate between said antifriction-rollers in a plane at a right angle to the direct-ion of movement of the plunger, cams fixed 011 the opposite sides of the edge of the wheel, one in advance of the other, and arranged to alternately engage said antifriction-rollers to reciprocate the plunger in opposite directions, a shaft rotated by said wheel, and mechanism operated by the shaft for reciprocating the mold in appropriateti med movements to correspond to the movement of the plunger, substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

JOHN BERRY.
